Two weeks ago my left testicle swelled up to twice it's normal size. I took Ibuprofin and the swelling went down. The swelling has retuned agian and this time it's been 6 days and the swelling hasn't went down. I am a married white male and have had sex 2 times while the testicle has been swollen. I have no pain while urinating, but I do have a low grade pain in this testicle. I had played alot of golf prior to the onset of swelling the first time. I waited a week and when the swelling was gone I played several rounds again and a day later the swelling returned. I work construction and typically lift heavy objects but not recently so I can't understand how golfing could cause this. I had a head cold a month ago but it ran it's coarse without medication. I don't have insurance so I can't afford alot of tests, is this something that can be diagnosed in a walk-in care center? Do you have any idea of what this could be?

You could have a hernia. You would need medical attention for this as it can turn very serious if not treated. Plus a swollen testicle is never anything to mess around with. You need to see a doctor. Some hospitals have charity systems for people who do not have insurance.
